  • an air conditioning method for a vehicle is provided.
  • the air conditioning method 10 comprises the following processes. It should be noted that although one possible sequence is shown in Fig. 1 , the invention is not limited thereto. In other examples, the sequence of the processes shown in Fig. 1 may be changed.
  • the air conditioning method 10 determines an ambient temperature inside the vehicle in step S102, determines an operating state of a temperature regulation unit and a minimum air volume of an odor regulation unit in the operating state in step S104, receives the setting of an intensity level of the odor regulation unit in step S106, and determines an air volume of the odor regulation unit in step S108 according to the ambient temperature determined in step S 102, the operating state and the minimum air volume determined in step S104 and the setting of the intensity level received in step S106.
  • the basic principle of the air conditioning method 10 will be described by taking fragrance as an example, the release of scent such as the fragrance may be precisely controlled by means of these above steps of the air conditioning method 10, achieving the effect of purifying air.

  • the air conditioning system 302 will affect the operation of the fragrance system 304 to some degree.
  • the operating state of the temperature regulation unit may be determined prior to configuring the operating mode of the fragrance system at least in part on the basis of the operating state thereof.
  • the minimum air volume of the odor regulation unit may be determined on the basis of the operating state of the temperature regulation unit.

Where possible, if there are multiple fragrance levels available for selection, settings including fragrance level selection may also be received in step S106.
  • the air conditioning method 10 determines the air volume of the odor regulation unit in step S108 according to the ambient temperature detected in step S102, the operating state determined in step S104, and the setting of the odor regulation unit received in step S106.

  • the process of determining the air volume in step S108 may specifically comprise: stopping the air volume output of the odor regulation unit where the detected ambient temperature is higher than a first threshold. For example, after the vehicle is exposed to the blazing sun, the temperature inside the vehicle is high, turning on the odor regulation unit in this situation will result in dissipation of lots of fragrances, etc. In some examples, if the temperature inside the vehicle is higher than 40°C, the odor regulation unit is no longer turned on, thereby reducing unnecessary consumption. Referring again to Fig. 3 , the fan 343 in the fragrance system 304 is used to control the output air flow so that the air flow output can be stopped by adjusting the fan 343 of the fragrance system 304.
  • the air volume of the odor regulation unit comprises the basic air volume at the intensity level, and the basic air volume at each level is pre-calibrated by the following method.

  • the following table shows an example of a basic air volume setting determined on the basis of the operating state of the thermostat unit (assuming that the fragrance system 304 has only two levels).
  • Calibration may be performed by means of on-site calibration and theoretical calculation, which will not be described in detail herein.
  • the results of calibration may, for example, be stored in tabular form to be recalled in the process of determining the air volume.

For example, if the ambient temperature and the operating state of the temperature regulation unit are simultaneously considered, a configuration solution as shown in the following table may be formed.
  • the superposition of the compensation air volume and the basic air volume is taken as the air volume of the odor regulation unit; otherwise, the minimum air volume is taken as the air volume of the odor regulation unit. In this way, it is possible to avoid the reverse flow described above in the case of being less than the minimum air volume.

  • the compensation herein and in the context of the present application may also be either a positive compensation or a negative compensation.
  • the operating state comprises a fan air volume of the temperature regulation unit 202
  • the odor regulation unit 204 is configured to determine the compensation air volume on the basis of the fan air volume of the temperature regulation unit 202.
  • the following table shows a setting of the compensation air volume where only the fan air volume is considered.
  • the compensation air volume may be increased, thereby more facilitating the release of fragrance of the fragrance system 304 from the second air passage 341.
  • the odor regulation unit 204 is configured to determine the compensation air volume on the basis of the ambient temperature where the ambient temperature is not higher than the first threshold (with continuing reference to the above example, for example, 40°C).
  • the following table shows the setting of the compensation air volume where only the ambient temperature is considered.
  • the air volume of the odor regulation unit 204 may be determined as: L7 + d2.
  • the compensation air volume may be set slightly larger to ensure that more fragrance molecules remain in the interior space of the vehicle.
  • the odor regulation unit 204 is configured to determine the compensation air volume also on the basis of the outside air circulation ratio of the temperature regulation unit 202.
  • the following table shows the setting of the compensation air volume where only the outside air circulation ratio is considered.
  • the compensation air volume of the odor regulation unit 204 is set where the fan air volume of the temperature regulation unit 202, the ambient temperature, the outside air circulation ratio of the temperature regulation unit 202, etc. are considered separately, but these factors may also be combined to set the compensation air volume of the odor regulation unit 204 (for example, according to at least one of the factors). For example, if the ambient temperature and the operating state of the temperature regulation unit 202 are simultaneously considered, a configuration solution as shown in the following table may be formed.
  • the odor regulation unit is configured to: take the superposition of the compensation air volume and the basic air volume as the air volume of the odor regulation unit where the superposition of the compensation air volume and the basic air volume is greater than the minimum air volume; otherwise, the minimum air volume is taken as the air volume of the odor regulation unit. In this way, it is possible to avoid the reverse flow described above in the case of being less than the minimum air volume. In other examples, it is also possible that the odor regulation unit is configured to stop the air volume output of the odor regulation unit where the superposition of the compensation air volume and the basic air volume is less than the minimum air volume.
  • a vehicle comprising any one of the vehicle air conditioning systems as described above.
  • the vehicle equipped with the air conditioning system will be capable of precisely regulating the degree of fragrance release.
  • a computer-readable storage medium in which instructions are stored, and when the instructions are executed by a processor, the processor is enabled to perform any of the air conditioning methods described above.
  • the computer-readable medium in this application includes various types of computer storage media, and may be any usable medium accessible to a general-purpose or special-purpose computer.
  • the computer-readable medium may include a RAM, a ROM, an EPROM, an E 2 PROM, a register, a hard disk, a removable hard disk, a CD-ROM or another optical memory, a magnetic disk memory or another magnetic storage device, or any other transitory or non-transitory media that can carry or store expected program code having an instruction or data structure form and be accessible to the general-purpose or special-purpose computer or a general-purpose or special-purpose processor.
  • Data is usually copied magnetically in a disk used herein, while data is usually copied optically by using lasers in a disc. A combination thereof shall also fall within the scope of protection of the computer-readable media.
  • the storage medium is coupled to a processor, so that the processor can read information from and write information to the storage medium.
  • the storage medium may be integrated into the processor.
  • the processor and the storage medium may reside in an ASIC.
  • the ASIC may reside in a user terminal.
  • the processor and the storage medium may reside as discrete assemblies in a user terminal.
